Safety mechanism for handgun and rifle trigger

ABSTRACT

A safety mechanism for handgun useful for preventing shooting by toddlers, having a lock ring assembly, having means to match the trigger finger of adults only, and a box assembly, having means to enable the shooting exclusively performed by said adults.

FIELD OF THE INVENTION

The present invention relates generally to the field of handgun safety. More specifically, the present invention relates to a safety mechanism for rendering the trigger of a handgun inoperative by a child.

BACKGROUND OF THE INVENTION

In the United States alone, there are 200 million privately owned small firearms. It is estimated that every seven minutes, a death is caused by a child who gains access to a firearm belonging to his parents or to another adult. This is because the child believes the firearm to be a toy, or simply does not know the dangers involved in handling the firearm. The problem is especially prevalent with toddlers 6 to 14 years of age. Parents often hide loaded firearms in their homes in places where they do not believe children will find them, but the location of the handgun often becomes known and the child is severely injured or killed playing with it.

This situation has led to the development of a variety of different safety devices and mechanisms that are designed for preventing unauthorized or unintentional use of a handgun or other firearm. Some devices employ trigger or barrel locks, which require removal or deactivation of the lock prior to shooting of the firearm. Others work on the basis of electronic locking systems that recognize, and thus only allow operation by an authorized user. Another way to prevent unauthorized access to a firearm, which is commonly used, is to lock the firearm (and the ammunition) in a safe or locked closet or drawer.

The following patents are hereby incorporated by reference and are meant to serve as examples of the prior art in the field of safety devices or mechanisms for firearms: U.S. Pat. No. 5,367,811 to Sansom relates to a trigger lock device that includes a lock assembly that is positionable between a firearm trigger and a firearm frame within the trigger guard. The lock assembly is arranged so as to discourage access to the firearm by children and the like by providing for ease of access to the firearm by adults comprehending the ease of disengaging the lock structure. U.S. Pat. No. 4,813,252 to Ray relates to a locking device for firearms which prevents firearms from being removed by children from the walls from which they are being displayed. U.S. Pat. No. 5,361,526 to Campbell relates to a child resistant quick release firearm safety and security device that is inserted into the loading port of a firearm. The device must be freed form the firearm prior to operation of the firearm. U.S. Pat. No. 5,191,158 to Fuller et al. relates to a trigger guard for a firearm. The trigger guard is essentially a clamping mechanism that overlies at least part of the trigger that has do be shifted in order to allow for operation of the trigger. All of the cited patents are hereby incorporated by reference in their entireties.

DETAILED DESCRIPTION OF THE DRAWINGS

The present invention provides a useful safety mechanism for handgun, designed in a manner shooting said handgun by toddlers is prevented. According to the present invention, said safety mechanism comprising a lock ring assembly, having means to measure the diameter of the trigger finger be higher a predetermined width, and a box assembly, having means to enable the shooting by adults only.

It is in the scope of the present invention, wherein said measuring means are calibrated to about 17 mm, which is the average diameter of the trigger finger of an adult. It is well acknowledged in the present invention that children age of 6 to 13 years old, hereto defined in the term ‘toddlers’, are having an average diameter of said a trigger finger in the range of 13 to 14 mm. Those toddlers are having unfit Pin-Lock key, because they are not able to move all the safety latches at once and thus the unauthorized shooting with the handgun by toddlers is prevented.

In the scope of the present invention, the safety mechanism hereto described is thus a hybridization of Measurement Device with a Pin Lock. The following description is thus provided, along all chapters of the present invention, to enable any person skilled in the art to make use said invention and sets forth the best modes contemplated by the inventor of carrying out this invention. Various modifications, however, will remain apparent to those skilled in the art, since the generic principles of the present invention have been defined specifically to provide for an improved safety mechanism for handgun.

The term ‘handgun’ is especially a pistols or revolvers, yet is also referring to any weapon comprising a trigger, and most particularly to non-automatic, semi-automatic or automatic rifled-bore rifles, smooth-bore shotguns, hunting weapons, revolvers having a cylindrical cartridge and magazine containing pistols. The term ‘handgun’ as defined above is referring to either single action or double action handguns.

In this respect it is acknowledged that in order to fire a handgun, two specific actions must take place: Step 1: The mainspring must be compressed to generate potential energy. This is often done by cocking the hammer. Some handguns, however, do not have hammers, and the mainspring is directly connected to a spring-loaded striker (the firing pin). Step 2: The mainspring must be released, converting the stored potential energy to mechanical energy. All handguns (revolvers, semi-automatic pistols, and Derringers) must perform these two steps in order to discharge the cartridge. The action of a handgun refers to the mechanism used to perform these steps.

There are three general types of actions commonly used on handguns, each performing the two basic steps slightly differently:

Single Action—When the trigger is pulled on a single action handgun, it performs only Step 2—release of the hammer from its cocked position. In single action handguns, the hammer must be cocked manually (Step 1). It is acknowledged that today, most handguns for civilian use acquires said single action mechanism.

Double Action—When the trigger is pulled on a double action handgun, both Steps 1 and 2 are performed. The hammer is cocked and then released by pulling the trigger. Since the process of cocking the hammer compresses the mainspring, the force that must be applied to the trigger of a double action handgun is greater than that of a single action gun. The hammer of a double action handgun, however, can be manually cocked.

Double Action Only—Double action-only handguns function essentially the same way as double action handguns, except it is not possible to manually cock the hammer. In the present invention, double action only handguns will be discussed and referred as double action handguns.

The term ‘trigger finger’ is referring in the present invention to the finger squeezing the trigger. Most often, the said is the pointing finger of the right hand. The trigger finger touches the trigger on one spot, named the digital pulp. It is the core of the present invention, wherein the diameter of said trigger finger is higher 17 mm, an indication for adult using the handgun. The term of said ‘digital pulp’ is referring to the fingertip or to the pad of the trigger finger, which enables the trigger to move backwards, and thus provides the handgun to shoot. Usually, the final step before shooting, also know as ‘the squeezing of the trigger’, comprises a gradually upwards concaved movement of said digital pulp along the trigger.

The term ‘safety-catch’ is referring in the present invention specifically to a certain safety latch (303) which is located adjacent to the trigger, having gradually elliptical or polygonal shape (see elliptical shaped 303A). Said safety-catch is having a protruding axis (303 b) and a pin member (303 c) attached to at least on rim of said axis. In case that the trigger finger is squeezing said safety-catch in the movement defined above, the aforementioned protruded pin member (303 c) is been pointed towards the trigger guard to a certain positioning and is further completely accommodated in a groove (603) located in the trigger guard.

Reference is made now to FIG. 1, presenting the safety mechanism according one claim of the present invention, generally comprising the two main assemblies:

(I) a lock ring assembly having (i) a trigger in communication with the fire mechanism of the handgun, (ii) a ring having a inner diameter with predetermined width of 15 to 19 mm, designed to accommodate the trigger finger of an adult; and (iii) at least one safety latch.

(II) a box assembly adapted to accommodate said ring assembly, having; (i) a body having at least one locking element; and (ii) a box cover, entrapping the lock ring assembly to the trigger guard.

A lock ring assembly (3), which is designed to be attached to the handgun's trigger (1) is entrapped inside the aforementioned box assembly. This lock assembly moves at a press of the trigger finger together with the trigger (1) on a predetermined course inside the box assembly, to enable the shot.

The lock ring assembly comprising a ring base (3) and a ring cover (4). Additionally and most importantly, said assembly comprises one or more safety latches (see for example two safety latches 301 and 302). Said latches are placed in the groove cuts in said ring (401) and (402), and the ring cover (4) locks the ring assembly together. The ring cover which fits on the trigger (1) by its trigger channel (403), has grooves (401) and (402) cut to fit the edge of one or more safety elements defined below, and thus allow it to be locked.

The box assembly box assembly is comprises of at least two parts: a body (6), which contains one or more, locking elements. In particularly, two locking elements (701) and (702) provided useful. In addition, said box assembly comprises an adjusting grip triangle (5) and box cover (7).

The body (6) is designed to latch on the trigger guard (2) by sliding on it from the left side of the gun, and adjusting its grip to the trigger guard by fastening the triangle (5) by turning the screw (501) clockwise.

The box cover (7) designed to clamp to the box thereafter by one or more lock screws, such as (601) and (602), that inserted through it, to lock unto their threaded locations on the box body (6). Thus, locking up the box assembly on the handgun's trigger guard (2).

FIG. 2 presents the safety mechanism according to one embodiment of the present invention, especially adapted to handguns having a double action mechanism. This figure reflects that the ring assembly is useful measuring tool and the box assembly is an effective lock, both interact with the other as a matching set of a Key and its Pin-Lock.

In order to shoot the handgun, the user has no other choice but to insert his trigger finger defined above into the circle of a lock ring (3). Otherwise the user could not pull the trigger (1), which the lock ring (3) attached to it backwards (i), thus to bring the trigger to its firing position. By doing so, the finger circumference is pushing the one or more safety latches (301) and (302) to outward direction through the grooved lock ring, putting them ready in position to perform their locking functions as proceeded.

Only in use of double action handguns, the trigger has to pull backwards to complete the first cocking action. Therefore, the locking mechanism is not permitted to lock the trigger to the box before the first action is completed, because it would be rather useful at load the gun with the said finger resting on the trigger. In this step the handgun is load and locked inte aforementioned first action position. Only an adult who his trigger finger is having a circumference of above 17 mm may push all the safety latches (301) and (302) far enough to perform the act of separating the locking ties between the locking elements (701) and (702) respectively, and the ring cover (3) to the box (6), and thus release the trigger to perform the shot.

If the adult shooter chose to shoot, he has to complete the second step of the double actin mechanism defined above, in order to fire the handgun. In said step, the said shooter shall find that the safety latches (301) and (302) are acting as lock pins, somewhat similar to the door lock mechanism. Thus, at the time said safety latches are been pushed by the shooter's trigger finger to reach their predetermined locations, the safety latches enabled to release the locking elements (701) and (702) by lifting the tooth against the pressure of its spring, away from the groove of the groove (402) of the ring (3), and hence pushes the locking element out of the groove in the ring corner. Thus, unlocking the ring (3) facilitated the movement of the trigger towards a firing position.

In one preferred embodiment of the present invention, the above mentioned safety mechanism is comprises of a safety-catch, having a lock ring assembly and a box assembly adapted to accommodate said ring assembly. The lock ring assembly comprises interalia a trigger in communication with the fire mechanism of the handgun; a ring having a inner diameter of about 15 to 19 mm, and most preferably 17 mm, designed to accommodate the trigger finger of an adult; one or more safety latches, and preferably two said latches; and a safety-catch defined in detail below, characterized by either elliptical or polygonal shape. The said box assembly is adapted to accommodate said ring assembly. Said box assembly is comprises interalia a body having one or more locking elements, preferably two such elements, and a box cover, entrapping the lock ring assembly to the trigger guard. The aforementioned safety mechanism is especially designed to enable the shooting only whenever said trigger finger is touching all said safety latches, and side safety latches are in communication with all said locking elements.

According the said embodiment, at least one safety-catch (303) is pushed by the trigger finger's circumference into the ring (3). This pushing motion also turns it around its axis.

Thus, it changes the position a square tip, also referred hereto in the term ‘pin member’ (303C) appended to said axis, to be in stationed in a match position to a groove (603) located in the body cover. Thus, the trigger is allowed to be squeezed backward (i) toward a shooting position. It is acknowledge hereafter that extra precaution was taken to prevent a toddler from using a stick as wide as an adult trigger finger in order to facilitate the forbidden shot. In this manner it is also acknowledged that attention was given to the fact that clever toddlers are capable of inserting an element thicker then its finger, in order to squeeze the trigger. Therefore, the present invention presents a novel and practical approach wherein the said safety-catch (303) is designed to be inserted in its ring groove beyond the internal circumference of the lock ring (3). Only a human finger comprising a digital pulp defined above can cause this squeezing action and that because by pulling the trigger finger inside the circumference of the lock ring, the digital pulp is elastic enough to protrude beyond the diameter of the ring, to a short distance of about one millimeter.

Hence, according to one embodiment of the present invention, said safety-catch is an ingredient of the ring assembly, and located on the back location on the ring, facing the trigger. Said ring further comprising a groove cut (403) adapted to fit said safety-catch by means of size and shape, thus enabling said safety-catch to penetrate the width of said ring, and similarly providing said pin member (303 c) to spin along the axis (303 b) and to be accommodate completely in the groove (603). Only when said pin member (303 c) is in groove (603), the trigger is provided to be squeezed and the safe shooting is enabled.

Still according to most similar embodiment of the present invention, said safety latch (303) is located on a the trigger, which comprising a groove cut (similar to the 403) adapted to fit said safety-catch by means of size and shape, thus enabling said safety-catch to penetrate the width of said trigger, and similarly providing said pin member (303 c) to spin along the axis (303 b) and to be accommodate completely in the groove (603). In this embodiment, the mechanism of action said safety-catch is separate from the mechanism of said safety mechanism defined above and may stand alone as a safety mechanism for a handgun.

As pointed out before, the average diameter of the trigger finger of an adult is about 17 mm wherein the average diameter in toddlers is in the range of 13 to 14 mm having the aforementioned unfit Pin-Lock key, because they are not able to move the safety latches (301) (302) and safety-catch (303) at one. A toddler may be able to load and perform the said first action, but on the second action the lock ring assembly will remain latched to the box, by at least one of he locking elements and thus shall not allow the trigger to move on to its predetermined firing position.

Reference is made now to FIG. 3 presenting a safety mechanism according to the present invention, especially adapted to a single action handgun. This safety mechanism is mainly comprising a box assembly and a lock ring assembly. The box is built according to one embodiment of the present invention by two parts. The body (6) contains the lock (7) and one or more ducts, here (603) and (604). It is additionally comprising an adjusting grip triangle (5) and a box cover (605). The body (6) is designed to latch on the trigger guard (2) by sliding on it from the left side of the gun, and adjusting its grip to the trigger guard by fastening the triangle (5) by turning a screw (501) clockwise.

The box cover (605) is adapted to attach to the box by one or more especially designed lock screws, here (601) and (602), that are inserted through it to lock unto their threaded locations on body (6). Thus, the lock up the box assembly on the handgun's trigger guard (2). This box contains the lock ring assembly (3) that is designed to be attached to the handgun's trigger (1) and move at a press of the trigger finger together with the trigger on a predetermined course inside the box, to facilitate the shot.

The ring assembly is comprises a ring base (3) and a ring cover (605) that contains in-between themselves the one or more safety latches, here (301) and (302) and a safety-catch (303).

Referring again to FIG. 3, presenting the mechanism of the safety mechanism defined in the present invention, especially for single action handguns. In order to shoot, the adult user has no choice but to insert his trigger finger into the inner circle of the lock ring (3), otherwise he could not pull the trigger (1) backwards (i) which the lock ring (3) is attached to it, to bring the trigger to a firing position. By doing so, the finger's circumference is pushing the one or more safety latches (301), (302) and the safety-catch (303) in outward direction through the lock ring, thus enabling their unlock abilities.

When the handgun is ready to shoot position, an adult only can push all said safety latches and safety catch far enough to perform the act of separating the locking ties of the ring box, and thus to release the trigger to facilitate the shot. In case an adult chose to fire the handgun, he shall find that the said safety latches are acting as a lock pins, somewhat similar to a door pin lock. Only when all said latches and catch are effectively pushed, the lock is released and the fire is enabled.

It is also acknowledged that the mechanism of the safety-catch (303) in the single action handgun is much similar to the one defined above for double action handguns.

Reference is made to FIG. 4, presenting an electronic mechanism for the safety mechanism defined in the present invention. Said electronic embodiment comprising a box assembly, a lock ring assembly and the electronic circuit assembly having power supply from a disposable battery or any other effective, light weight means.

One embodiment is referring for the aforementioned electronic safety mechanism incorporated in either single or double action handgun. In principle, the control box is having two parts: the body (6) and the box cover (7). Said body contains the locking servo (9), and locking micro-switch (303), and the one or more grip screws, here (701) (702) and (703). Said box cover (7) has an opening adapted to accommodate the trigger finger, had a kidney shape, and also contain grip-screw holes, for grip screws, here (701) (702) and (703).

The body (6) is adapted to latch on the trigger guard (2) by sliding on it from the left side of the handgun. And adjusting its grip to the trigger guard by fastening the grip screws (701) (702) and (703) through the cover (7) into their threads in the box (6). These screws are of the lock screw type, which requires a special fit screwdriver in order to open or close said screws. Thus said screws are adapted according to the present invention to lock the box onto the trigger guard (2) of the handgun.

The box (6) contains the locking assembly (3) that is adapted to be attached to the handgun's trigger (1) on a designed course inside the box, and to enable the shot. The ring assembly is composed of a ring base (3) and a ring cover (4) that contains in-between themselves the safety latches (301), (302), (303) and (304). Those safety latches act in the manner similar to a modern door's lock, which its mechanism is to be defined below.

The said embodiment of an electronic version of the safety mechanism defined in the present invention operates by using the ring assembly (3) as a measure tool, adapted to indicate the case in which the user of said handgun is an adult, and more specifically, its finger trigger (i.e., the key); and the box assembly to be the lock of the said safety mechanism. Both above defined assemblies interact simultaneously as a set of a key and its lock. The shooting sequence in this embodiment is much similar to the one defined above. Nevertheless, few adaptations are acknowledged: the user inserts his trigger finger into the inner circle of the lock ring (3). Avoiding this will disable the trigger to pull backwards to the firing position. By doing the same, the trigger finger is pushing the safety latches, here, (301), (302), (302) and (304) in outward direction through the said ring, thus enabling the unlocking step.

At the time the handgun is ready to shot, only an adult who has a trigger finger with circumference diameter higher about 17 mm, can push the safety latches far enough to perform the act of connecting the micro witches to thus to close the electric circuit (804) at the ring (3) to the servo lock (9), and thus release the trigger to enable the shot.

Wherein an adult chose to fire the handgun, all the safety locks are simultaneously pressed, to activate one or more micro-switches, here (801), (802), (803) and (804) that are lined up on the circuit (804). This special arrangement provides a direct current to flow from the positive pole of a battery (8) to the negative pole of the servo, to the negative pole of the battery. The servo's electromagnet pulls the lock tongue (9) into the body and releases the same from the trigger to enable the shot.

According to another preferred embodiment of the present invention, an additional and external lock is used to provide extra safety to the handgun. Reference is made thus to FIG. 5 presenting unloaded position having a firing position (A), locked position having a no-firing possibility (B) and (C), wherein (605) is a grove especially designed to accommodate the key, (606) is the lock-release member (607) is the locking cylinder, and (608) is the lock-pins assemble.

Reference is made now to FIG. 6, presenting a safety-catch for handgun comprising: (i) a trigger in communication with the fire mechanism of said handgun; (ii) a catch having means to swing trough an opening in said trigger; and (iii) a trigger guard having a groove, designed to accommodate said safety latch whenever said trigger is twisted by the digital pulp of the trigger finger.
